Cold start/run problem
So, here it is. I've replaced the entire ignition system, all power and ground cables, vacuum lines and the carb. When it's cold outside, she'll start and seems to idle fine. I give her a few minutes and try to get her moving but she doesn't wanna go. Unless I get the RPMs up to around 1500 she just stutters and starts to die. I think the electric choke is opening too quickly but I'm not sure how to adjust that. Once she's up to operating temps she's fine. Vacuum off the manifold at idle is at 20 when the engine is warm. I'm going to measure when cold to see if the heat is expanding the gaskets and sealing a possible vacuum leak. Also, I removed the Linear Vacuum Regulator thing because it advancing the ditsributor at idle so the only vacuum advance, warm or cold, is coming from the carb. I had also read something about headers effecting cold weather running and starts. Any help would be appreciated. Thanks in advance.
